Using coal ash to make concrete is one way to physically change the coal ash and encapsulate the toxic elements while creating a valuable material. Concrete is typically made by mixing sand, rock and water with cement — a dry powder often made from burned limestone.
The most significant uses of coal are in electricity generation, steel production, cement manufacturing and as a liquid fuel. Different types of coal have different uses. Steam coal also known as thermal coal is mainly used in power generation.
Coal in the cement industry Cement manufacturing consists of raw meal grinding, blending, pre calcining, clinker burning and cement grinding. Limestone, CaO, SiO2, Al2O3 and Fe2O3 are crushed and milled into a raw meal. This is blended and preheated in a preheater cyclone.

Portland Cement Manufacturing Process Description17 Portland cement is a fine powder, gray or white in color, that consists of a mixture of hydraulic cement materials comprising primarily calcium silicates, aluminates and aluminoferrites. More than 30 raw materials are known to be used in the manufacture of portland cement, and these
The price of coal varies by coal rank and grade, mining method, and geographic region.. Coal is classified into four main ranks—lignite, subbituminous, bituminous, and anthracite—depending on the amounts and types of carbon it contains and the amount of heat energy it can produce.
A number of different types of cement are manufactured, by varying the ratio of the raw material and/or by adding some additional materials. Some of the most common cement classifications are: 1. Ordinary Portland Cement. 2. Rapid hardening cement, 3. Ultrarapid hardening cement.
